The Boston Red Sox will be aiming to return to the World Series for the first time since their last championship victory in 2013 when they open the American League Championship Series against the defending champion Houston Astros as +125 underdogs on the MLB series prices at sportsbooks monitored by OddsShark.com. The Red Sox overcame two straight years of postseason disappointment in their American League Divison Series clash with New York, eliminating the Yankees in four games capped by a 4-3 victory as +130 road underdogs on Tuesday. The team will hope to take advantage of home-field advantage in their ALCS battle with Houston, and are listed as -125 favorites in Saturday night’s Game 1 matchup versus the Astros at Fenway Park. A late-season swoon had Red Sox fans on edge entering the postseason. For a third straight year, Boston struggled down the stretch, going 7-8 over its final 15 contests, including losses in four of six meetings with the Yankees. While the club rebounded nicely in their ALDS win over New York, they have been unable to maintain their perch atop the World Series odds, and enter the weekend closely trailing the Astros as a +215 bet on those MLB futures.
